Letters P/ateat No.A 107,202, dated September 6, l1870.

IMPRovnMsN'r 1N NUMB'nRrNe-Mncnmns.

The Schedule referred-to in these Letters Patent and making part of the same.

v-r-bw--Q To all whom it may concern Be itknown that I, JAMES D. SMITH, of Washington, in the county of Washington and District ot' Columbia, have invented certain Improvements in Numbering-Machines, of which the following is a specification; reference being had to the accompanying drawing. y

My invention relates to1numhering-machines of that class in which a series of disks, with numbers on their peripheries, are mounted ina yoke, so as to rotate automatically, and consists in vthe construction and attachment to the left side ofthe yoke of a novel device or contrivance for placing readily and conveniently, to the lcft of the line of figures on the disks, ot' one or more figures or letters, as may be desired.

In the drawing- Figure l is a perspective view of my device. l v Figure 2 is a side view of' the same, showing its attachment to thc yoke.

Figure 3 is a iront view of the same-as attached to the yoke, together with the numbering-disks.

Figure 4 is a side and end view of the same, detached, as constructed for adding asingle letter or figure. l

'Figures 5 and 6 are side and end views of parts, detached, for increasing or adding additional numbers o1: figures.

As is well known, in the numbering devices of the class referred to, each additional disk with the figures upon it increases the numbers ten-fold, and that, tor most purposes, three or tive disks are sufficient.

Heretofore, however, when higher numbers were desired, it has been customary to attach, either to the hub about which the disks rotated, orto the left side of the left disk,.a small post'with the required figures upon it. But, in order to do this, itis necessary to stop the machine, and take the disks ont of the yoke,

and then attach the post, which takes time, and occasions a good deal of delay.

The object of my invention is to provide a device for accomplishing the salue result without the nece's- -sity and trouble of taking the machine apart, and thus avoiding the usual loss of time thus occasioned.

In constructing my device', I make a post, A, of the form or shape clearly shown iu ligs. l, 3, and 4, and consisting oi' a shank, a, shoulders b, and upright c, and connect it to thelifont' end of the left side of the yoke B oi' a numbering-mach ine, by inserting its shank a ina suitable mortise cnt therein, and fastening it there by ascrew, C, passing through the side of the yoke, and engaging in an opening in the shank a, pro- .vided with a screw-thread for the purpose, as clearly shown in figs. 2 and 3.

The under side oi' the shoulder b rests upon lthe end ofthe yoke B, to which it is fastened, and is so constructed as to extend far enough beyond the inner face I of the end of the yoke'to bring the side of the upright' c close to the side of the disk next to-it in the yoke, as clearly shown in iig. 3. i Y

The end of the upright c is provided with a dove*- tailed groove or socket, inwhich is inserted a small post, e, having a figure or letter upon its cuter end;

and this small post e is of the proper length ,to bringthe end of the latter, with the figure thereon, just iu line with the figures ou the disks, as clearly shown in figs. 2 and 3. l

To the left side of the upright cis connected a plate, f, by means of two small pins, g, attached to it, which enter corresponding holes or sockets, h, in the upright c, as shown in figs. 4 and 5; and to the left of the plate f another plate, i, is-placed, the whole being securely bound together by means of a screw, j, passing through them and engaging with the upright, as clearly shown in fig. 3.

The upper ends of the plates t' and j rest upon the shoulder b of the post A, and their lower ends are provided with dovetailed sockets, in which are insert ed, respectively, small posts,k and l, each having'a figure on their outer end, and of the requisite length tobring their figures iu line with those oh the disks in the machine, as clearly siiown in iig. 3.

Having thus described the consti-notion of my device, its operation, in connection with the class of numbering-machines referred to, will be readily nn-V derstood.

A yoke, B, with a series of disks, D, mounted therein in the usualmanner, and with figures on their peripheries, is shown in ugs. 2 and 3, and, in connection, with them is shown my device, attached with the.

small poststherein, as above described, when the lower numbers are printed, as,for instance, those below one thousand, the small posts e, k, and l should not be insei-ted, but when they reach ten thousand, the post e can be inserted, afterward .the posts`k 'aud l, successively, as the higher numbers are reached, there being ten of each. g i

It will thus be seen that, by means of my device,

the numbering-machinev may, 'whenever desired, be` made toreach up into the higher numbers wit-houtV having to delay it only long enough to insert a -small post with the required figure upon it, in its socket,

and that this device can be readily attached and removed without weakening, injuring, or in. any way iucumhcring the machine.y

It is obvious that any number of plates desired may be connected to post A, by making the shoulder or base b of a size suitable for the purpose, and the small the post A withone or more removble pltesnf and posts e k l, 85e., may have letters or figures or other i, when constructed and arranged substantially as device upon them. herein described, and for the purpose set forth.

Having thus described my invention, JAMES D. SMITH. That I claim is Witnesses: In a. numbering-machine having :t yoke, B, with ro: H. B. MUNN,

tzttug disks D mounted therein, the combina-tion of PHIL. T. DODGE.
